Simona Halep came through her Australian Open fourth round tie with a much-needed comfortable 6-3 6-2 victory after Saturday’s third round match lasted nearly four half.

The world number one came out on top of a tight opening set before running away with the second over Naomi Osaka in Melbourne.

Many had expected a tighter match after Halep suffered an ankle injury in her opening match and was then on court for three hours and 45 minutes on Saturday in beating Lauren Davis.

However, the highly-rated Naomi Osaka from Japan was no match for the top seed.

The opening six games were tight before Simona broke her opponent on her fourth service game in the opening set which was the catalyst for taking control of the match.

Her defensive skills minimalised Osaka’s power and she didn’t let the highly-rated 20-year-old back in the match by making only five errors in the second set, whilst taking all three break points that came her way.

Halep showed no signs of an ankle injury suffered earlier in the tournament and sets up a tie with world number six Karolina Pliskova in the quarter-final.

Pliskova came through a tight victory over fellow Czech Barbora Srycova 6-7 6-3 6-2 in two hours and 41 minutes.

It is the third time that the Simona Halep has reached the last eight at the Australian Open and the first time since 2015.
